Abstract (en)

[origin: WO9524237A2] A guidewire for use with a catheter has varying radiopacity as well as at least one radiopaque marker in its distal end. In one embodiment, the guidewire includes a shaft having a distal radiopaque coil supported by and attached to a distal portion of the shaft and a proximal radiopaque coil supported by and attached to an intermediate portion of the shaft. The proximal and distal coils are spaced apart from one another. The distal coil may be more radiopaque than or equally radiopaque to the proximal coil such that when viewed under fluoroscopy, the highly radiopaque coil will define a dark image whereas the more proximal radiopaque coil will define a moderately radiopaque image or both will define a dark image. The area between the two coils will appear white. Between the coils, at least one radiopaque marker band is attached to the shaft. The marker bands provide several reference lengths for a physician. A polymer sleeve encases the marker bands and the shaft between the first and second coils providing a uniform outer diameter to the distal region of the guidewire. In another embodiment, the proximal coil of the first embodiment is absent and the polymer sleeve extends proximally of the radiopaque marker bands. In a further embodiment, a radiopaque coil having varying pitch along its length is supported by and attached to a distal region of the core wire.
